During my internship I worked in the Network Security Operations Center (NSOC), which is in charge of the network stability of the network. NSOC’s focus is to ensure the integrity of MCI’s network and systems as well as the protection of its strategic and intellectual assets through an ongoing concerted program of prevention, detection, investigation and response to fraud and abuse. There is also a team that was more involved with inside of NSOC which is called the Incidence Response Operations Center (IROC). The projects that I took place in were to respond specifically to network security alarms generated by the intrusion detection sensors that are located within the MCI network. These sensors examine packets of data and determine suspicious activity based upon past experience as well as customized triggers. The IROC response capability allows all network security incidents to be analyzed and the appropriate responses initiated as determined by the event’s level of risk. In addition, the IROC security knowledge base, which stores previous incident resolutions, resides within one organization and helps the planning of future security solutions as determined by trending of the actual security alarms. The IROC security analysts utilize an alarm system that presents the alarms with detailed information. It includes the sensor location, signature number, a description of the alarm, a source and destination IP address, severity level, and the date and time stamp. The security analyst investigates the alarm starting with the knowledge base entry if this exists. A knowledge base entry is a resolution that was previously implemented to resolve this type of alarm. If there is no knowledge base entry then the analyst begins to investigate ... ... middle of paper ... ...ures that they use to monitor the network and they felt like several of them which was created years ago may not be needed are might even needed to be modified to fit the network operations of today. This was very difficult starting off trying to apply the knowledge about signatures that I was taught and what I read. I had to rely on a few of our senior engineers to help get through the first couple of signatures and then after I got the hang of it became evident of what I need to do. I was in charge of dissecting thirty signatures and on twenty-two of them changes was made to them regarding the results of my project. There are hundreds of thousands alarms a day and through my results that cut the IDS from triggering on over ninety-five thousands plus alarms. With this such of decline in false positive alarms will make the job for the IROC team easier after I am gone.
This would include developing a process for security collaboration among participating organizations. If a working group of security officers has been formed, this group might continue to meet in order to compare notes on possible security threats to the RHIO, review of activity reports, or to discuss real or alleged incidents involving the data exchange systems. Collaboration among security officers will probably require them to focus on an agreed-upon definition of security incident. The group probably will want to prioritize their limited time to deal with significant threats to the system, not just review reports that have little or no security significance. It is almost inevitable that as a result of human error, a technical failure or a novel attack that some security incident or privacy breach will occur. It is extremely important that the RHIO has agreed upon procedures for incident response, reporting and
It is best to prevent security incidents from occurring in the first place – therefore prevention should be a top priority for the IT staff at CEG. The National Institute of Standards and Technology (NIST) recommends five main categories of incident prevention; risk assessments, host security, network security, malware prevention, and user awareness training (Cichonski P., Grance T., Millar T., & Scarfone K., 2012 p.24). Risks of the various types of possible security incidents should be identified and prioritized based on likelihood and potential harm. Risk assessment should be periodic and ongoing. Host security is achieved by hardening each host on the network. Host hardening includes keeping current on the latest software patches, enabling and monitoring audit logs, and assigning permissions based on a system of least privilege. Network security is primarily concerned with securing the perimeter of the network to prevent unauthorized intrusion. This includes the use of firewalls, intrusion detection systems (IDS), securing VPN, and blocking unnecessary ports. All hosts on the network must run and regularly update malware protection software. And all employees should...
1.) (3 points) The US Computer Emergency Readiness Team (US-CERT) publishes what are called Technical Cyber Security Alerts and Vulnerability Notes and these documents alert users to potential threats to the security of their systems. Select a Technical Security Alert or Vulnerability Note published in the last twelve months that has a network related component to it and research the reported problem and the suggested solution (if one is available.) Analyze and describe the problem, and the solution paying close attention to the network related issues that it raises. We are interested in reading your analysis, and not a cut-and-paste of what is on the website. The listing of recent Technical Security Alerts can be found at: http://www.us-cert.gov/cas/techalerts/ and the listing of Vulnerability Notes is at http://www.kb.cert.org/vuls
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Internships completed by students in certain degree programs are quite popular in most colleges and universities. An internship is used so classroom based learning in a degree program can be applied to practical situations in the real world (Jordan, Burns, Bedard & Barringer, 2007). When students are placed with an agency, there is a real possibility that a portion of students will witness actions they believe is unethical or illegal. During a study conducted within four universities, many students that participated in an internship program within the criminal justice system reported that they had observed behavior they suspected to be illegal behavior for a law enforcement agency. (Jordan et al. 2007). Due to this ongoing problem, colleges

Containment is the most important role to be played in an incident respond. These are the practice of the strategies which gets followed when there is an attack like Distributed Denial of Service Attacks ("Uf it security," 2011). In our Lockheed Martin company, we prepare ourselves for any circumstances so our employees can act upon the situation. Instead of wasting time in what needs to be done now we prepare ourselves for future attacks. The way containment process needs to be followed is to first determine which part of the system contains malware viruses and detecting this issue would be the first task in incident response strategy. The time when that one system is detected then our company will be isolating that specific system to limit
I had many responsibilities and duties as a teacher assistant/chaperone. Such as arriving at the assigned school for bus and student pick-up at 8:00 a.m. assisting teachers and counselors with Daily Opening Activity, with Math and Reading as well as Arts/Folklore classes. Escorting students to and from the bathroom. Supervising students during breakfast and lunch and assisting with clean up. Being responsible for picking up and returning materials to the GEAR UP office. Attending weekly Staff and Team meetings to discuss the past week and plan for the weeks ahead.
Due to their complexity and importance to information security, two security systems, Network Intrusion Detection/Prevention Systems (NIDPS) and Security Information and Event Management systems (SIEM), will be explored in this paper. Both have multiple functionalities, including threat-detecting capabilities, and are widely considered essential tools for adequate network defense, particularly in the goal of fortifying valuable assets in the face of an advanced threat. Understanding these systems is vital for any security operation tasked with defending significant networks.
Network management planning and security planning involves identifying the best and most appropriate systems and hardware that the firm can use to better manage network and plan security systems. Therefore, the management required me to examine the best software and hardware systems in the market place that the company can adopt to enable it to manage the network and security. The management required me to advice on the implementation procedure of various plans that are going to be adopted. My responsibility also involved finding out or predicting the impact of the plan on the future operations. They required me to evaluate the challenges the company might face while adopting the changes in the network management plan and security plans.
They are also there to make sure that Jules is on time for all her meeting and they make sure that Jules knows the necessary information when going into the meetings.
Internship is the practical exposure given to the graduating students that provide a bird-eye view of work culture and experience. Supervised internship is an important preparatory stage for number of careers like, medicine, journalism, legal services, accounting and education. In these programs aspirants get the award of degree credit for supervised work performed with the specified work place. This also provides enhanced knowledge backed with practical experience to them. The prime facie focus of the program is on the injection of practical knowledge into the minds of the students to great extent. The internship will make the aspirants involve directly with the application of knowledge in the controlled work environment.
The policy and chances provided for studnets are different in each country. In Australia, the unique program is "The Navitas Professional Year Program". It is common program that provide internship for engneering, computing and accounting. For foreign student, they need permanent visa. In new zealand, professional internship provides chances for studnets in abundant major. They would like to offer students paticipated the good experiences and working environment. In American, professional internship becomes very polular in recnet years.
Throughout my one hundred and twenty-hour experience with the Gloversville Police Department, I learned many skills, values and the ways of this Police Department. Many of the calls and situations I went to often could relate to a certain theory that I learned in any of my law classes. I would recommend any student majoring in Criminal Justice to try to take an internship with a local law enforcement agency. I am currently signed up for the civil service test for Gloversville Police Department, If I do qualify for the Police I believe that this internship will give me a huge head start.
A critical part of network planning involves setting up of security mechanisms. Deploying the network with security configuration provides superior visibility, continuous control and advanced threat protection across the extended network. Additionally, security procedures define policies to monitor the network for securing critical data, obtain visibility, mitigate threats, identify and correlate discrepancies.
